[SOLVED] Dual screens and Gaming and Nvidia

smakked · 2010-03-03 01:58:07

Have been trying to get this to work for a while now.
I have 2 screens which work well in kde, but when i want to play games on one screen ie: Nexuiz, it span across 2 screens.
I have tried all things in the wiki and still cannot stop this behavior. Any suggestions on how to make my games show on a single screen?

Note : It sued to work a few weeks ago but i did fresh install of arch now i cant get it working, cant post Xorg till later tonight when i finish work.

Disable one of the screens?
I believe for this to happen the program would actually have to support it. As far as nexuiz is concerned, it sees one big screen.

can you disable a screen with a command before you fire up a game?

Try disper in AUR.

Why not use separate-X. You can't drag windows between screens that way, but you can limit the game to one screen (and have other stuff running on the other screen, your chat program for example).

Yeah tried that but still spans across both screens.

Will look at disper

you should also be able to use xrandr to disable one of the screens

When using separate-X don't use xinerama, make sure the screens are slightly offset from each other. You'd need mouse-wrapscreen for the mouse to travel over.

Do you use TwinView? I had this same problem. To solve it, I added the following to the "Device" section of xorg.conf:

Option "MetaModes" "1280x1024,1280x1024; 1280x1024"

This will disable the second screen when playing a game in full-screen. Not the best solution, but at the moment it is all that I have been able to do >.<

Yeah, for TwinView I did the following in mine (you can also achieve it via the nvidia-settings GUI)

Option         "metamodes" "CRT: nvidia-auto-select +1680+150, DFP: nvidia-auto-select +0+0; CRT: NULL, DFP: nvidia-auto-select +0+0"

There are two settings in that line, namely

CRT: nvidia-auto-select +1680+150, DFP: nvidia-auto-select +0+0

which says DFP (my HDTV, primary monitor) is at its native reported res, and CRT (a flatscreen monitor hooked up by VGA, secondary monitor) is also at native res, but shifted off to the right (so I can drag windows and things on it it)

and

CRT: NULL, DFP: nvidia-auto-select +0+0

which says if a game goes fullscreen and changes the res to the primary monitor's native res the "CRT" monitor will turn itself off for the duration of the game and turn itself back on when finished. It's not ideal as the other monitor turns off when gaming but it's the most reliable method I've found.

DISCLAIMER: I only learnt enough about it to get it to work for me and then prompty backed up xorg.conf and never worried about it again, so the explanation may not be 100% technically correct. It does work though.

I also have something very similar to Sheepeh

Option         "metamodes" "DFP-0: 1680x1050, DFP-1: 1280x1024; DFP-0: 1680x1050, DFP-1: NULL;"

smakked · 2010-03-05 14:23:13

Yeah thanks fellas got it working now

Option         "metamodes" "CRT: nvidia-auto-select +1920+0, DFP: 1920x1080_60 +0+0; DFP: 1920x1080 +0+0"

thast what i needed to get right
